You should not refer to the past in your answer. To say that you want to be a receptionist because your field of study was related to the job, or because you had the same occupation in the past, would indicate a must.
You should show them your desire to have this job–and not a must.
I suggest you to talk about the future, your motivation to do the job, and the nature of it. You should also be careful about your tone of voice and the way you talk about this occupation. Show enthusiasm, show them that you enjoy doing the things receptionists normally do.
Every one of us has some skills and is good in doing something. I believe that people enjoy talking to me, that I am a good listener, and that I can identify their needs and help them to satisfy them. That’s my reason for applying for receptionist role.
I would like to become a hotel manager one day, and believe that a role of a receptionist is a first step on my long journey to the position of a hotel manager.
